Yes, it will fit on the trailer. I'm sure for that size trailer the axle weight rating is 3500 lbs so you should be good in that aspect as well. But one thing you should be mindful of is that if the floor of your trailer is made of metal mesh. If you plan on hauling this mower around a lot the metal mesh flooring will start to sag where the drive wheels go and potentially poke a hole in the tires. So just keep a eye on that. If it does show signs of wear its a simple fix.
